Steer-by-Wire (SBW) system consist of steering wheel system and front wheel system. The reactive torque control algorithm of steering wheel system was designed in this paper. To verify the control algorithm, the SBW system is modeled using the bond graph method. Aim of the control algorithm is controlling the steering wheel motor to express reactive torque from roads. The control algorithm of the steering wheel system used the torque map to reactive torque control. Using the filter, the current of the front wheel system enter the steering wheel system. Front wheel system has two motor, independent actuating. In developing the tie-rod actuating SBW, the Ackerman Geometry was used for improving the vehicle stability. Verification simulation and performance simulation show that the SBW controller was available in this study.

Generally, the vehicle dynamics performance is influenced each chassis subsystem with some trade-off relations. One of the systems is a suspension system that related vehicle ride and handling performance. Especially the roll stiffness tendency of a vehicle can be significantly changed, if the suspension component is actively controlled. This study is presented the Active Roll Control Stabilizer Bar System (ARC) for improving of the vehicle roll motion and vehicle dynamic performance by control of roll stiffness distribution. This paper describes a fundamental understanding of the theory and application of the ARC system analysis. Based on the study on ARC, we can make a proposal on the integrated control system using Continuous Damping Control (CDC) and Active Roll Control stabilizer bar (ARC). This research arranges and defines the ARC functionality and performance limits, then shows how to improve such a limit using by CDC (Continuous Damping Control) on the vehicle performance with ARC system. Finally, this paper proposes the vehicle dynamics performance integration control strategy and show the synergy effect through the integrated control vehicle simulation.
